Résumé
Osteoarticular infections due to non-typhoidal Salmonella are rare, occurring with an incidence rate of 0.1-0.2%. An immunocompromised state and the existence of sickle cell anemia are known risk factors for development of septic arthritis due to Salmonella. In this report, we describe a patient with septic arthritis of the left knee caused by non-typhoidal Salmonella . An 82-year-old woman visited the emergency room presenting with left knee pain, fever and dyspnea. The patient had osteoarthritis and was treated with oral analgesics, but not with an intra-articular injection. Upon assessment of the patient's joint fluid and blood culture results, non-typhoidal Salmonella (Salmonella group D) was detected. Arthroscopy-guided irrigation and debridement, and administration of oral antibiotics (fluoroquinolone) over six weeks were required in order to achieve a full recovery from the infection.
